Something just occurred to me: Rokinon 14mm + Speed Booster!

Okay, so was looking at the 14mm 2.8s and saw one for 4/3. That's probably the most solid 28mm-e you could hope to get for any mount, much less 4/3-m4/3. But since it's actually a full-frame lens, why not buy a Nikon or Canon one and Speed Boost that s***? If I'm not mistaken, you'd end up with a 20mm f2 equivalent lens with what should be INSANELY sharp results.

And even with the Speed Booster you'd be looking at about the same price as a 12mm f2.

Someone should try this out on one of the larger bodies!

but at the end, 12 would be smaller, one stop faster, native with autofocus... why bother with an adapted lens, for the same price and probably similar IQ?

It would be wider and the speed would be the same (speed-boosters give you a one-stop "boost"). Personally, I prefer native AF lenses though.

The native 12mm is the most sensible purchase - but I'd be interested to know what the Samyang 10mm 2.8 is like with a speed booster.

forgotted these :p

in any case, you get an heavier, larger lens, no af. with the 12mm, if you want to go wider, you can add a good wide converter, and still get a small fast and native lens.

an option could be take a 12mm samyang for m4/3 and a wide converter, you will save some money, and get another FL with, still @ f/2

Just be aware that the Samyang can have QA issues, so make sure you buy from someone where returning is painless.

Here's one wide open and one of the more difficult shots of the day with the bird on the other side of a shaded tree and i had a narrow gap to even sight it, this is with the Roxen Reducer on the Cine version.
Shows how we are all different as I love the handling and feel of the Cine version and whilst it is heavy it's similar to the 12-60 so suits me.

and in reply to the OP, whilst I love the manual lenses and speed boosting them once your in the same dollar area as the native 12mm you may as well get the O12 and get the AF benefits and size/weight benefit.

I don't particularly want the 12mm, because a) NOT WIDE ENOUGH!, b) apparently outresolved by the 12-40 which can be had for not that much more than the 12mm, c) not that much better than the 9-18.

Using wide converters on the 12mm and all that doesn't work if you're actually after ultimate image quality. Not saying I am, but if I was using an E-M5 or E-M1 (the latter of which I have), my 12-60 and MMF-3 is probably heavier than the SB and 14mm. Plus as someone mentioned somewhere else, the VC 58 1.4 would become a 85 f1...*drool*

Yeah that should be a sweet sweet combo. Would love to see a comparison with the native portrait lenses.

The Metabones Speedbooster and 14mm combo is 687grams in weight. Just weighed them.
